request: local MRV for martian

[wheaton5]

So a bit of an insider request as I know 10x uses a system to track all of the currently running mrp instances and gives the pid and the url as well as the pipestance name. This really helps with organization when running multiple analyses simultaneously.

We've internally replaced mrv with something newer and more powerful. We've been calling it Martian Enterprise, as can be guessed from https://github.com/martian-lang/martian/blob/master/src/martian/cmd/mrp/main.go#L83). Though we don't have a schedule for it, it is our intent to release it eventually. I'll pass your request on, and maybe we can at least release it in an open-source, unsupported form sooner rather than later.
